SPECIFICATION forming part of Letters PatentN 0. 702322, dated June 10,1902. I Application filed February 27, 1902. Serial No. 95,949. (Nomodel.)

To all whom it may concern: I

Be it known that I, FRANCIS M. MEOUM, a citizen of the United States,residing at Chico, county of Butte, State of California, have inventedan Improvement in Disk-Plow Attachments; and I hereby declare thefollowing to be a full, clear, and exact descriptionof the same.

My invention relates to improvements in that class of plows in whichconcavo-convex disks are journaled and revoluble'upon a suit able frame.

My invention consists in a means for changing the lines of travel of thebearing-wheels, whereby the plows may be held up to their work and madeto cut furrows of greater or less width or to regulate the cut in landof variable quality.

It also comprises a'connection of said wheels with a swingingdraftpole,-wh ereby the wheels are turned in unison with the movement ofthe pole, and a means for. multiplying the rate of movement of thewheels with relation to that of the pole.

My invention also comprises connections by which the raising andlowering of the frame are effected and details of constructiomwhich willbe more fully explained by reference to the'accompanying drawings, inwhich-.

Figure 1 is a plan view 'of plow. Fig. 2 is a side elevation. Fig. 3is adetail of the device for operating the front portion of the plow.

A is the main frame, made of channeled or angle iron or otherwisesuitably constructed for strength and rigidity.

2 is abearingand guide wheel mounted upon a crank-axle 3 at the leftside of the frame, and 4 is a similar bearing-wheel mounted upon a bentangularly-placed axle 5, which axle is swiveled and turnable in abracket 6, attached to the rear portion of the main frame.

7 is'a third bearing-wheel upon the right and at the front ofthe'machine. This wheel is also mounted upon a bent or angularlyplacedaxle 8, and this axle, as well as the axle 5, is so bent that the wheels4 and 7 stand at an angle, bracing against the action of the disk plows9, which are journaled upon shafts standing at an angle with thedirectionpf travel of the plow. These wheels 4 and 7 are designed totravel in furrows previously made by the plows and by their ani gularposition .to prevent the plows from crowding to one side, and the wheel2 is intended to travel upon the land or' unplowed portion. By means ofa pawl-carrying lever 10 and a segmental rack 11 the crank-axle 3 may beturned and the frame correspondingly raised or lowered with relation tothe bearing-wheels.

Myinvention consists in combining with a than the rate of movement ofthe pole; and.

it also consists in such aconnection of the spindle of the front wheel 7with the lever 18 that the front portion of the frame will be raised anddepressed and its movements con trolled by theoperation of the singlelever 18.

The pole 12, towhich the draft-teamis attached, is pivoted, as shown at13, and it may be held stationary and prevented from turning by means ofa pin 14 passing through it and the frame. When the pin isremoved, thepole will swivel or turnupon its pivot or pivot-bolt 13 by any movementof the tea from one side to the other.

The shaft or axle 8, upon which the front wheel 7 turns, stands at anangle orincline, as previously stated, and it is bent so as to form avertical portion 8. This portion of the shaft extends up through abracket or frame 15, in which it is turnable andslidable, the firstmovement being for the purpose of changing the direction of travel ofthe wheel 7 and the second for raising and lowering this portion of theframe with relation to the standard 8 and wheel. This latter movement iseffected as follows: To the top of the standard 8 is fixed an arm 16.This arm is connected by a rod 17 with a pawl-lever 18, suitablyfulcrumed, as at 19, and by moving this lever, which is fulcrumed to themain ICG frame, it will raise this frame, and the yoke or bracket 15,sliding upon the standard 8,

will allow the frame to be raised or depressed with relation to thebearing-wheel 7. A segmental rack, as at 20, serves to hold the lever 18at any desired point of adjustment.

In order to turn the standard 8, and with it the angular wheel-shaft 8and the wheel 7, I have shown an arm 21, which is firmly secured to thestandard 8 by a set-screw 22 or other equivalent fastening. The oppositeend of this arm is perforated and slidable upon a rod 23, the upper andlower ends of which are fixed in a bent yoke 24, which lies within thebracket or yoke 15. Both ends of this yoke 24 are perforated to looselyfit the standard 8, which is slidable through this yoke as Well as thebracket or yoke 15. This yoke 24 forms a lever and may be turned withinthe bracket 15 by a power applied to any part of it projecting away fromthe standard 8% This power is here shown as applied by means of a lever25, connected with the lower part of the yoke 24, as shown at 26, andthis lever is fulcrumed upon the pivot 13, about which the pole 12 isturnable.

When the pole 12 is fixed by means of the bolt, as at 14, the wheel 7and the wheel 4 are turnable in unison as follows: The outer end of thelever 25 is connected by a rod or chain 27 with a hand-lever at 28,which leverisfulcrumed to a part of the main frame convenient to thehand of the operator, who may be riding upon the seat of the plow. Theswiveled wheel-shaft 5, upon which the Wheel 4 is journaled, iscontrolled by a lever 29, fulcrumed, as shown, and connected by a chainor rod 30 with the lever 28. One rod, as 27, may be connected with thelever above its fulcrum, and the other, as 30, may be connected with thelever below its fulcrum, so that the movement of the lever 28 in eitherdirection will pull the connecting-rods 27 and 30 in oppositedirections, and thus change the direction of travel of the wheels 4 and7. The connection between the lever 25 and the yoke 24 may be made byslotting the lever longitudinally and connecting with the yoke by meansof a pin upon the yoke which is slidable in the slot. When the pole 12is released from the locking-pin 14 and allowed to turn by the movementof the team, it will turn with it the yoke or bracket 15, which is fixedrigidly to it and projects to one side, and while the lever 28 is heldin a fixed position by means of its pawl and ratchet it will be manifestthat the lever 25 will also be held stationary. This lever being thusheld stationary, the yoke 24, which is carried with the bracket 15, willbe given an independent movement with relation to the lever 25, so thatthe connecting-pin 26, sliding in the slot in the end of the lever 25,will act to turn the standard 8, the shaft, and the wheel 7 faster thanthe pole turns by reason of the multiplication of speed caused by apeculiar connection of the lever 25 and the lever-yoke 24. This movementwill then change the line of travel of the wheel 7 with considerablerapidity and is useful where the plow encounters ground of varyinghardness, in which the plows are liable to be thrown in or out and tomake an irregular furrow. This tendency can be entirely corrected bychanging the angle of travel of this wheel, this movementbeingindependent of any changes which may be effected by the movement of thelever 28, and which changes are communicated to both the wheels 4 and 7.

Having thus described my invention, what I claim, and desire to secureby Letters Patout, is-

1. The combination with a disk plow of front and rear bearing and guidewheels, in clined axles upon which said wheels are turnable, said axlesbeing swiveled and turnable with relation to the main frame, leverconnections with each of said axles and connections between said leversand a single hand-lever whereby both wheels are turned simultaneouslyand in the same direction.
